To all whom it may concern Be it known that I, Josnrrr Grisrrin, a citizen of Hungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Interchangeable Boot and Shoe Heels, of which the following is a specification.

This invention relates to heels for boots or shoes, being more particularly intended for embodiment in heels, having rubber or like tread elements, the invention having for an object to provide a novel means for detachably securing the tread elements in place to ermit of these elements being readily interchanged in a pair of boots or shoes, it being well known that most people wear the heels at one side or the other.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a side View of a shoe having my improved heel app-lied thereto.

Fig. 2 is a central longitudinal vertical sectional View of the heel.

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2.

Fig. l is a plan view of the detachable element. 7

Fig. 5 is a horizontal sectional view taken on the line 55 of Fig. 2.

As here embodied my improved heel comprises a top plate 10, preferably of alumi-' num, and which is secured by suitable means to the shoe, indicated generally at 11, spikes 12 being here shown as embedded in the plate and projecting upward therefrom to engage in the shoe. This plate is formed on its underside with a recess 14 which extends rearward from the front edge of the heel to a point near the rear edge of the heel, this recess being dovetailed along its sides as shown so as to cause the detachable element to be held in place. I

This detachable element is in the form of another plate 15 which has a projection 16 on its upper face which is complementary to the recess 14 in the upper plate 10, this plate forming a backing element for a rubber tread member, and may be of the same material as the plate 10. The top face of this projection formed with-a recess in which'is securedas at 19, thewidened baseelemen't 20 of a spring latch 21 which has an integral finger piece 22 projecting forwardly through the front edge of the heel, this latch normally engaging behind a shoulder 23 on the plate 10, to thereby hold the detachable plate 15 in position, a slot 24 being formed in the latter plate to permit of depression of the latch to disengage it from the shoulder 23.

This detachable plate 15 has fixed thereto a detachable rubber tread member 26, the plate being formed on its underside with a dovetail recess 35 which enters from the front end thereof, and which receives an upwardly projecting and outwardly flaring rib 36 extending along the sides and rear edge ofthe rubber heel element 26. The inner side faces of this rib are dovetailed and tapered as shown in Fig. 5, and a complementary wedge block 87 is inserted in the space in the recess 35 surrounded by the said rib 36 and bears against the latter, thus holding the tread element 26 in place. The latch 21 is formed with a second and rearwardly facing latch hook 21" which engages in front of a shoulder formed by the rear wall of a notch 38 cut in the top of the block 87, this notch being of sufficient depth to allow the latch 21 to be swung down to free it from the shoulder 23 on the top plate 10. As will be apparent when the detachable element has been removed from the shoe 21 the latch can be swung away from the shoulder in the blocks 37 and the latter removed, permitting of replacement of the tread element, while simple interchanging of the heel can be effected as above set forth.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A heel comprising a permanent top plate, a backing element, a tread element on said backing element, a block retaining said tread element engaged with said backing element and a double latch holding said block in position on said backing element and said backing element in position on said top plate.

2. A heel comprising a permanent top plate having a recess on the underside thereof, a backing element having a projection adapted to engage in said recess to hold said backing element on said plate, said backing element having a recess on the underside thereof, a tread element presenting a rib on its top face extending around the sides and rear thereof, and adapted to en gage in the said recess, a Wedge block Within the confines oi the rib adapted to hold the latter in engagement With the Wall of the said last named recess, and a double latch acting to hold the backing element in place on the top plate and the Wedge block in place 10 engaging the said rib.

3. A heel comprising a permanent top plate a backing element, a tread element on said backing element a block retaining said tread element engaged with said backing element, and a common means holding said block in position on said backing element and said backing element in position on said top plate.

In testimony whereof I have afiixed my signature.

JOSEPH GASPAR.
